Subdirectory 'catalog' in 'image' directory is hard coded

[nmpetkov]

In order to be able to make multi-site installation, we need to specify different directory for uploaded images (I mean not multi store in one database, but multi-sites with one code base and different databases and image directories). Currently it is not possible with constant DIR_IMAGE (if changed, then images are not visible from http). Proper directory to be configurable is "catalog" subdirectory, but it is currently hard coded in:
https://github.com/opencart/opencart/blob/master/upload/admin/controller/common/filemanager.php
with several statements like:
DIR_IMAGE . 'catalog/'
and
DIR_IMAGE . 'catalog'

One possible solution could be to add a constant next to DIR_IMAGE in config.php, for example:
define('IMAGESUBDIR_CATALOG', 'catalog');

If this is acceptable solution, I can make PR for this, otherwise please advice how to proceed.

so your building a multi vendor mod where clients have their own login in the admin. ask in the forums not here~! this is for development of opencart script and not help you build a site for clients!
